Also keep in mind, the issue with resets a lot of times is due to a bad filter cap on the +5vdc. You will not see that if you use a DMM on DC voltage, on DC you will see a lower 5vdc value due to the increased ripple. Try setting your meter to AC and check it. You probably see a lot more than 3.6mV.

Regardless, if you getting resets on that game, and it is the original supply, I would replace all the electrolytic caps on the supply before doing anything else. It's cheap and it will most likely fix your problem and a couple future ones.

The MPU is Rottendog, I see no where where the PS was called out as a Rottendog.

Again, if it is the ORIGINAL supply that's never been reworked, do a cap job.

+1 and if you look close at it a lot of times it 'pisses' out the bottom and your see a spot on the board.

One would only email them if it were a Rottendog P/S,,, which it has never been stated it was.

It was stated it was a Rottendog MPU.
